Roll crusher, which can also be called double roll crusher, is used for the coarse and secondary crushing of high strength and hardness materials in cement, chemistry, mining, building material, refractory and coal mine industry.
The installation of roller crusher in the grinding system can increase production, reduce the overall energy consumption and improve the production capacity. With simple structure, it is convenient to use and maintain and the particle size of the discharged products can be adjusted. The dust shield within the crusher can prevent the ground materials from splashing, and in addition, the noise is lowered.
The gap between the rollers can be adjusted according to the specific size of the materials to be crushed within a range. Appropriate products are discharged from the bottom of the crushing space after adjusting the gap. Low speed revolution and high pressure are the working principles of the roller crusher, and the intense pressure produced by the rollers extrudes the materials in the crushing space.
There are some notes needed to be paid attention to according to the characteristics of double roller crusher. Iron removing equipment should be fixed in front of the roller crusher to prevent non-crushing materials from dropping into the rollers and destroying the crusher. The surface of the rollers will be abraded after being used for a long period, so the regular examination and maintenance are necessary.
